What does it mean to drive the dog (JOE) to the south?

In the 12 branch, "Zi Chou Yin Mao Chen Si" and "Shen You Xu Hai at noon" collided with each other.

Zi Chong Wu Chou, Shen Chong Mao Chongyou and Chen Chong Si Chong Hai,

When choosing the auspicious day of the zodiac, we should pay attention to the fact that the earthly branch of the day does not conflict with the genus of the parties. The so-called dog rush is because the earthly branch of the selected day is Chen, which collides with the zodiac dog. Rush means that the heavenly stems of that day are Geng, and Geng belongs to Jin Kejiamu.

Simply put, people born in JOE should avoid Chen Geng Day whatever they do.

"Drive the dog (JOE) to the south" is a hint that this day is not good for people born in JOE and should be avoided.

"An Shan" means that the direction of evil spirits is in the south that day. No matter what you do, you should avoid that direction.
